The machine is running embedded and we did not put a "deregister NIC" button in the GUI -:). Off hand I can think of no process that could come close to deregistering the device. > or... we really see a memory corruption. :-/ Hmmm...so you think that the chances of this being a hardware fault (in the NIC) are slim?
